TECHNICAL FIELD OF THE INVENTION
The present invention relates to safety glasses that can be used, for example, as swimming goggles and dust-proof glasses.
[0002]
[Prior art]
BACKGROUND ART Conventionally, there have been protective glasses for protecting eyes such as swimming goggles.
[0003]
For this swimming goggle, I want to replace it with a prescription lens or polarized lens according to the user's eyesight, change the color of the lens to my favorite color, or change the density of the lens according to the surrounding brightness There are cases.
[0004]
For this reason, there has been a type in which a user can exchange lenses with respect to the frame (there is a hard frame or a soft frame made of a material that is relatively soft).
[0005]
However, when the frame is made of a soft frame (for example, refer to Patent Document 1), the frame may be deformed to form a gap with the lens, and water may enter. On the other hand, as shown in FIG. 13, when the frame body 21 is made of a hard frame (for example, see Patent Document 2), a packing (made of silicon rubber) 23 is interposed between the lens body 22 and the lens 22 in order to obtain watertightness. However, when the interchangeable lens is fitted into the frame, there is a problem that the packing is easily displaced and the replacement operation is difficult.

[0009]
In the protective glasses, since the outer peripheral area of the interchangeable lens is brought into contact with the elastic frame material, the elastic frame material allows fluid-tightness (water-tightness, air-tightness, etc.) with the outer peripheral area of the lens. Sealing) can be secured, and there is no need to interpose packing or the like.
[0010]
In addition, since the outer peripheral region of the lens is engaged with and fixed to the rigid frame material, the rigid frame material can ensure the resistance and deformation resistance during use as a whole frame body. In this way, it is possible to prevent the water from entering the gap from the lens due to the deformation of the frame.
[0011]
The fixing of the lens and the frame member may have some deviation which does not hinder use. In addition, the engagement between the outer peripheral region of the lens and the rigid frame material may be indirect through an elastic frame material (for example, the rigid frame material may be sandwiched by the elastic frame material in the outer peripheral region of the lens). Structure).
{Circle around (2)} A flange portion and a locking portion may be provided in the outer peripheral region of the lens. With this configuration, the thickness of the rigid frame member and the elastic frame member can be absorbed by the flange portion and fixed by the locking portion.
{Circle around (3)} The flange portion and the locking portion may be formed on the entire outer peripheral region of the lens or on at least a part thereof.
[0012]
It is sufficient that the flange portion and the locking portion are provided on at least a part of the outer peripheral region of the lens. However, if the flange portion and the engaging portion are formed over the entire outer peripheral region of the lens, the lens is securely fixed to the frame even when a force is applied during use. It is strong against deformation and excellent in strength.
{Circle around (4)} The locking portion in the outer peripheral region of the lens may be fixed by engaging with a rigid frame material.
[0013]
With this configuration, the locking portion in the outer peripheral region of the lens and the rigid member such as the rigid frame member are engaged with each other and fixed, so that the strength and durability are excellent.
{Circle around (5)} The knob may be extended to the lens. With this configuration, it is possible to suppress the attachment of fingerprints to the lens surface by working while holding the knob when attaching and detaching the lens.
{Circle around (6)} The cushion portion may be integrally formed with the face contact by the elastic frame material. With this configuration, the elastic frame material including the face contact cushion portion is excellent in moldability.
{Circle around (7)} The nose belt portion connecting the left and right frames may be integrally formed by the elastic frame material. With such a configuration, the formability of the elastic frame member including the nose belt portion connecting the left and right frames is excellent.
